  1. Question 1

    Q1. A 2 kg block is moving on a horizontal surface with a frictional force of 4 N. What is its acceleration?

    • A) -2 m/s²
    • B) 2 m/s²
    • C) -1 m/s²
    • D) 1 m/s²

    Answer: -2 m/s²

    Explanation: F = ma, so a = -F/m = -4/2 = -2 m/s², negative because friction opposes motion.
